Is Korea a third world country?

Answer 1

No. If by Korea you mean South Korea (since 'Korea' normally means the South, NOT the North; North Korea is a separate country and it's always referred to as 'North Korea'), the answer is an incredulous "Are you kidding?". Korea is one of the richest countries in Asia, with a very high standard of living. It's also one of the largest economies in the world, despite its small size. It boasts a very high-tech popular culture, with way faster internet than pretty much any other country, east or west. It's one of the world's leaders in robotics and consumer electronics today, as well as exporting a huge amount of popular entertainment products such as movies and TV programs all over the world. It's rich, advanced and progressive. Immigrants from other countries flock to Korea in search of a better life. North Korea could be referred to as being a third world country due to its under-development and poverty.

Answer 2

Korea, as in South Korea, is a first-world country. North Korea is a third-world hellhole.
